CLI Code Spike – Rethinking how I interact with the command line via C# a little bit. I have some spike code in which all these tests pass. Thoughts?

clitests.cs

public class CommandResolutionTests
{
    public void should_resolve_text_to_command()
    {
        "samplecommand".Called<SampleCommand>();
    }

    public void should_call_command_hello()
    {
        "samplecommand hello".Called<SampleCommand>()
            .Received().Hello();
    }

    public void should_call_command_save_with_file()
    {
        "samplecommand save --file=guybowling.png".Called<SampleCommand>()
            .Received().Save(Arg.Is<SampleCommand.SaveArgs>(x => x.File == "guybowling.png"));
    }

    public void should_call_command_save_with_output()
    {
        "samplecommand save --output=ProfilePic.png".Called<SampleCommand>()
            .Received().Save(Arg.Is<SampleCommand.SaveArgs>(x => x.Output == "ProfilePic.png"));
    }
}

public class SampleCommand
{
    public virtual string Hello()
    {
        return @"Hello World";
    }

    public virtual void Save(SaveArgs args)
    {
        // do stuff
    }

    public class SaveArgs
    {
        public string File { get; set; }
        public string Output { get; set; }
    }
}

So I got some good feedback that isn't here... I was informed to check out https://github.com/nessos/UnionArgParser, https://github.com/adamabdelhamed/PowerArgs, and https://github.com/DarthFubuMVC/fubucore.

Thanks for the feedback so far people!

The idea command line parser solution will have a fluent WebAPI written in F#, running the generated commands through Mass Transit.
